Class StepData

java.lang.Object
  wt.step.processor.stepParser.StepData

public class StepData

extends Object

A model of the data in a STEP/Part21 file to the level of individual StepEntities, but not linked/validated to a particular Express Schema.

Field Summary

private Hashtable	_entityBags
private Hashtable	_idMapping
private static STEPParser	_parser

Constructor Summary

StepData(InputStream stream)

StepData(String definitionFilename)

Method Summary

void	addEntity(Integer entityId, String name, Vector attributes) Adds an entity to the collection of step data so that 'same type' entities are grouped together and entity references can be resolved on demand.
void	dump()
Vector	getAllEntitiesOfType(String typeName) Gets a Vector of all Entities of the given type.
Enumeration	getEntityTypeCollections() Returns an iterator over the collection of all entity types found in the STEP file.
Enumeration	getEntityTypeNames() Returns an enumeration over the type names of the StepEntitys read from the STEP file.
StepEntity	getEntityWithId(Integer id)
private void	loadData(InputStream stream)

Method Detail

loadData

private void loadData(InputStream stream)
               throws ParseException

Throws:

ParseException

dump

public void dump()

addEntity

public void addEntity(Integer entityId,
                      String name,
                      Vector attributes)

Adds an entity to the collection of step data so that 'same type' entities are grouped together and entity references can be resolved on demand.

getEntityWithId

public StepEntity getEntityWithId(Integer id)

getAllEntitiesOfType

public Vector getAllEntitiesOfType(String typeName)

Gets a Vector of all Entities of the given type. All Entity references within the returned Entities are resolved to their actual StepEntity objects.

getEntityTypeCollections

public Enumeration getEntityTypeCollections()

Returns an iterator over the collection of all entity types found in the STEP file. Each element of the iteration is a Vector of StepEntitys.
The corresponding sequence of type names can be retrieved using getEntityTypeNames().

getEntityTypeNames

public Enumeration getEntityTypeNames()

Returns an enumeration over the type names of the StepEntitys read from the STEP file.
